Pentagon chief warns allies over NATO budget

“No longer can the American taxpayer carry a disproportionate share of the defense of Western values.” James Mattis, secretary of defense

BRUSSELS — Defense Secretary James Mattis warned NATO allies Wednesday that European defenses are at risk due to low military budgets, and said the Trump administration may scale back support for joint defense if other governments do not contribute more.

The stark warning put the 28-member alliance on notice that the White House has not backed down from Trump’s demands that other NATO members pay more for the military alliance that has been a keystone of global security for nearly 70 years.

“If your nations do not want to see America moderate its commitment to this alliance, each of your capitals need to show support for our common defense,” Mattis told a meeting of defense ministers at NATO headquarters.

“No longer can the American taxpayer carry a disproportionate share of the defense of Western values,” Mattis said. “Americans cannot care more for your children’s future security than you do.”

Mattis did not say how or how soon the United States would pull back if NATO members don’t increase military spending. But he didn’t suggest withdrawing from the alliance entirely or question its fundamental purpose, as Trump did in mid-January when he called NATO “obsolete.”

Nor was it clear if other nations will pay heed to Mattis. Czech Defense Minister Martin Stropnicky downplayed the warning, saying fellow ministers were not concerned.

“This is not the first time we’ve heard this” from U.S. officials, he said after the meeting.

The Obama administration also urged NATO members to boost spending, but didn’t threaten to cut support unless its demands were met. NATO took part in the U.S.-led air war in Libya in 2011, and has stepped up operations in Afghanistan and in Europe since 2014.

Indeed, ever since Russia seized Crimea and began backing armed separatists in eastern Ukraine in 2014, the Pentagon has sent reinforcements to NATO nations in Eastern Europe to reassure allies and to deter Russia from potential aggression.

Early last month, the Army sent 87 tanks, 144 armored vehicles and 3,500 troops to Poland in the biggest U.S. military deployment in Europe in decades.

The Pentagon also plans to construct or refurbish facilities, airfields and training ranges in Bulgaria, Estonia, Germany, Latvia, Lithuania, Poland and Romania.

Other NATO members also have boosted their forces in the region, including Canadian troops in Latvia, German troops in Lithuania, and British troops in Estonia. Only five countries — the United States, Britain, Estonia, Greece and Poland — meet the NATO goal of spending at least 2 percent of gross domestic product on defense.
